AUV Arctic Operations

Products Sonardyne to Protect MidEast Facility Sonardyne installed an integrated intruder detection system for an undisclosed strategic waterside installation in the Middle East. The contract included the deployment of a network of the company?s Senti- nel underwater sonars, seabed mounting systems, armored Þ ber optic cabling, onshore equipment shelters and a centralized command and control system. With global orders approaching 100 systems in 3 years, Sentinels are operational worldwide protecting energy infrastructure, coastal assets, vessels and strategic military assets. The system re- liably detects, tracks and classi Þ es underwater targets approaching a protected asset, providing security personnel with advanced threat warnings. The system is scalable to meet the needs of a single vessel right-through to the largest port and coastal borders. www.sonardyne-ms.com Underway CTD on Canadian Icebreaker While on passage from the Canadian west coast to the arctic, Depart- ment of Fisheries and Oceans (DFO) scientists from the Institute of Ocean Sciences (IOS) in Sidney, BC, were able to collect dozens of high quality 400m CTD pro Þ les across the Paci Þ c Ocean without stopping or slowing the icebreaker CCGS Sir Wilfrid Laurier. The researchers used the Oceanscience UnderwayCTD system. The DFO scientists have traditionally used expendable CTD (XCTD) probes, launched from the Laurier while slowing the ship to about 9 knots, from its typical transit speed of about 11 knots. While easy to deploy, the expendable probes do not match research-grade oceano- graphic instruments in accuracy and resolution, and are not ideal as a tool to monitor subtle changes and variability in the temperature and salinity Þ elds of the North East Paci Þ c, associated with climate change and moving fronts. www.oceanscience.com BioSonics MX Echosounder BioSonics offers the MX Aquatic Habitat Echosounder, a complete hardware-software solution for mapping and quantitative assessment of submerged plants, substrate classi Þ cation, and bathymetry. The MX uses scientiÞ c single beam sonar housed in a Pelican Case with an integrated DGPS and storage for the transducer, cable, and Þ ttings. It comes complete with Visual Habitat MX software, a powerful new data processing and visualization tool developed speci Þ cally for the MX. Visual Habitat MX software was developed in tandem with the MX sounder as a means to quickly and effectively present information in a clear and visually captivating display. Users can instantly generate color-coded maps showing data parameters for each transect includ- ing bathymetry, plant coverage, and substrate type. A toggle func- tion connects each echogram data Þ le with a map view of the transect plan. An integrated utility provides instant background mapping imag- ery over which habitat information can be superimposed. Data can be processed and maps can be generated within minutes of data collec- tion. www.biosonicsinc.com June 201260 MTRMTR #5 (50-64).indd 60MTR #5 (50-64).indd 605/31/2012 1:25:17 PM5/31/2012 1:25:17 PM
